APPARATUS FOR WASiHlNG OR SCRUBBING GAS.

SPECIFICATION forming part of Letters Patent N 0. 638,005, datedNovember 28, 1899. Application filed August 17, 1899. SerialNo."727,555.' (No model.)

To all whom, it may concern:

Be it known that we, SAMUEL CHANDLER, J r., and J OSIAH CHANDLER,subjects of the Queen of Great Britain, residing at Central Works,Kennington Oval, London, England, have invented new and usefulImprovements in Apparatus for Washing or Scrubbing Gas, of which thefollowing is a specification.

Cur invention relates to gas washers and I0 scrubbers of the kindwherein a series of plates, sheets, or boards or of clusters of the sameis arranged upon a rotating shaft or axle and partiallyimmersed in thewashing liquid in such a manner that as the plates are rotated all partsthereof will be successively immersed in the washing liquid and somaintained in a wet condition.

The object of our invention is to provide improved means for maintainingthe spaces or channels between the plates, sheets, or

boards and causing the gases which pass between the same to travel muchfarther before leaving them than heretofore, whereby the gas is moreeifectually purified, and for providing carriers of any shape or numberto distribute liquor over the surfaces employed. According to ourinvention the plates, boards, or the like are separated bydistancepieces of a breadth corresponding with the space which is to bepreserved between adjacent plates, the said distance-pieces being eitherstraight or curved or otherwise suitably shaped and being preferablyarranged in a series of concentric circles around the 5 axis of thewasher, spaces being left between the distance-pieces of each circle,while the distance-pieces of one circle are arranged opposite to thespaces between the distancepieces of adjacent circles, so that the gasin passing from the center of the drum to the exterior will have to flowin a zigzag or circuitous passage. It will thus be understood that thegas in passing through the apparatus is subjected to a large amount ofwetted surface and is more thoroughly broken up than heretofore. Thesaid distance-pieces are formed with hollows or recesses which raise theliquid as the apparatus rotates and allow it to drop again through andin contact Our invention will be readily understood by reference to theaccompanying drawings, in which Figure 1 is a transverse section ofapparatus constructed according to our invention, and Fig. 2 is alongitudinal section of the same. view and a section of one of theclusters of plates detached.

a a are the plates, sheets, or boards, and b b are the distance-piecesarranged between the same, a series of the said plates a a, with thedistance-pieces between them, being secured between the side plates 0 d,secured to a boss 6, mounted upon a shaft f, carried in suitablebearings in the ends of a casing g, which incloses the plates. Thiscasing g is divided by partitions h h into bays, in each of which aseries of plates is adapted 'to rotate and which at the bottom isadapted to be provided with the washing liquid, which as the plates arerotated keeps them constantly wet.

It will be noticed that the boss 6 has two flanges M, to which the sideplates 0 d are respectively connected, and that the fiangej is providedwith a series of openings 7c and has its face running in close proximityto the margin of an opening Z, formed in the adjacent partition 72,while the side plate 0 extends right down to the flange 2'.This'arrangement is provided in order that the gas to be purified as itflows from one bay to the next through the opening Z shall pass to theinterior of the cluster of plates, thence between the same, and thenceto the next bay, as indicated by the arrows in Fig. 2.

Figs. 3 and 4 are respectively an edge The plates at a of each series ofplates may be formed out of a single sheet of material or in a series ofsections. ings, the latter construction is adopted, each section beingof segmental shape, as shown in Figs. 3 and 4, and at its inner endresting on a bolt m, extending through the side plates 0 and d and alsothrough the flaugej, as shown in Figs. 1 and 2, while the said segmentis confined in posit-ion by another bolt at, extending through the sideplates c cl.

The distance pieces I) b, as hereinbefore stated, are arranged in aseries of concentric 50 with the gases flowing through the apparatus.circles, as shown in Fig. 1, and so that the As shown in the drawhalvesof each distance-piece are carried by adjacent segments, thisarrangement being provided in order that the apparatus can be readilyerected and transported, and that in case of necessity any cluster ofsegments can be removed for cleaning or repairs without disturbing anyof the other segments.

In Fig. 1 each distance-piece b is represented as being provided at oneend with a notch or recess 0. These notches or recesses serve as theapparatus is rotated for lifting the washing liquid and dropping it ontothe adjacent distance-pieces, so as to insure a most intimate contact ofthe gas to be purified with the liquid.

\(Vith the construction hereinbefore described it will be understoodthat the gas which passes from the center of each group of plates andbetween the said plates to the periphery of the group will be caused topass in a zigzag direction in the manner indicated by the arrows in Fig.1.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed, we declarethat what we claim is 1. In apparatus for washing or scrubbing gaswherein a series of circular plates, sheets or boards are carried uponan axle or shaft separating the said plates, sheets or boards by aseries of distance-pieces arranged in circles or rows with spacesbetween them in such a manner that the distance-pieces of one row orcircle are opposite to the spaces between the distance-pieces of theadjacent row or circle so that the gas in passing from the center of theapparatus to the periphery will be caused to flow in a zigzag orcircuitous course, substantially as described.

2. In an apparatus for washing and scrubbing gas, the combination withthe inclosing casing, of a rotating device comprisinga series ofcircular plates mounted upon a supporting-shaft and separated bydistance-pieces arranged in concentric rows with spaces between those ofeach row, thedistance-pieces of each row being opposite the spacesbetween the distance-pieces of the adjacent rows, each distance-piecebeing provided on one edge with a liquid-recess, substantially asdescribed.

3. In an apparatus for washing and scrubbing gas, the combination withthe inclosing casing provided with a series of partitions each having acircular central recess, said partitions dividing the casing intocompartments, of a rotary device in each compartment comprising the sideplates one of which is provided with a central aperture registering withand closely adjacent to the aperture in one of said partitions, a seriesof plates between said side plates and a series of distance-piecesinterposed between said latter plates arranged in concentric rows, thedistance-pieces of each row being separated by spaces and thedistance-pieces of each row being in line with the spaces between thedistance-pieces of adjacent rows, substantially as described.
